Abstract

In stationary Tokamak equilibria with poloidal and toroidal flows the density is no longer constant with a flux surface. The relationship between the size of the density variation and the direction and magnitude of the flow is examined. The case of a poloidal flow with no net toroidal velocity leads to a large density variation at moderate values of the Mach number. We show as an example that the reported anomalies in the density profiles measured in the PDX Tokamak in presence of strong neutral beam heating could be explained with many different flow patterns.
